Part A:
The ratios in the table are equivalent.
The two quantities in this table represent a proportional relationship.
The graph of the relationship would be straight line through origin
Step-by-step explanation:
Part A
The ratios in the table are equivalent.
Length: Cost
6 : 42 = 1 : 7
15: 105 = 1: 7
24 : 168 = 1:7
30 : 210 = 1 : 7
The two quantities in this table represent a proportional relationship.
If we take length = x, then cost =7x
When length = 6 , Cost = 7 *6 = 42
When length = 15 , Cost = 7 * 15 = 105
When length = 24 , Cost = 7 *24 = 168
The graph of the relationship would be straight line through origin
y = 7x
y -> cost and x -> length
When x = 0 , y= 0. so, this graph go through the origin
Part B:
$ 7 per foot

The arrow starts out at the -22 on the timeline. It moves back towards -24 which is 2 numbers down from the starting point and is why you’d be subtracting 2 from the -22. Finally, the answer to the problem is where the arrow stopped, or landed, which was -24.
Answer:
-22 - 2 = -24
Step-by-step explanation:
The answer space already has the minus sign so we can infer the number line is showing subtraction.
We start from -22 and jump to -24. This number line skip counts by 2 and we only jumped one unit, it means we subtracted by 2.
So we subtracted -22 by 2 and it is equal -24:
-22 - 2 = -24

5. Rectangle ABCD is graphed in the coordinate plane. The following are vertices of the rectangle: A(-1,-6), B(-1,-7), C(1,7), and D(1,-6). Given these coordinates, what is the length of side AB in this triangle? On the lines below, provide the length of the side as well as your reasoning for how you arrived at your answer.
Answers
Answer:
The legnth of side AB would be 3 units
Step-by-step explanation:
First, you would determine that both point A and point B would have the same y-coordinate of 1. Then you would determine the difference between the x values of points A and B. Since 5 (the x-value for B) minus 2 (the x-value for A) is 3, the legnth of side AB would be 3 units.

please mark me as brainliest and correct me if im wrong
You could either use the propotional method or unitary method, but I am going to be using the porpotional method since it is more quick.
Step 1
So first we would convert the numbers givin into a fraction by putting 5 over 140 and 20 over x which is the question mark.
Step 2
Then we would cross multiply, so multiply numbers that are diagonal to each other .140 would multiply with 20 and 5 would multiply with x.
Step 3
After we multiply (we do not multiply 5 with anything so it is just 5)we would have the equation , x times 5=2800. Since we need to isolate x we would take 5 and put it under 2800 so it would be 2800 divided by 5.
Step 4
After we divide 2800 by 5 we would have 560 which equals to x , making it the ounces needed to feed 20 animals at the shelter .
Summarise
To briefly explain this the way to find the answer would be 20x40 divided by 5.

The first thing we need to do is the math inside the parentheses:
(1 + 1/3) = 1 + 1/3 = 4/3
Next, we square the parentheses:
(4/3)² = 16/9
Now, all we need to do is subtract!
16/9 - 2/9 = 14/9
If you need to make it a proper fraction, your answer is 1 5/9, but if you leave it improper then 14/9.

If the point (3,-7) is the center of a circle and the point (8,5) is on the circle, what is the circumference of the circle?
(A) 13pi
(B) 18pi
(C) 25pi
(D) 26pi
Answers
Answer:
i think the answer is 25pi
The circumference of the circle is 26π, having center at point (3,-7) and a point on the circle is (8,5).
What is circle?
A circle is a round-shaped picture, that has no corners or edges, in geometrical figure it has the largest area for any given length or parameter.
The point of center of the circle 0 = (3, -7).
And the point on the circle C = (8, 5).
The radius of the circle = the distance between center and point on circle
Use the formula to find distance between two points,
The distance between two points A(x₁, y₁) and B(x₂, y₂)
Distance
= √(x₂ - x₁)² + (y₂ - y₁)²
= √(8-3)² + (5 + 7)₂
= √5² + 12²
= √25 + 144
= √169
= 13
The radius of the circle r = 13.
The circumference of the circle = 2πr = 2 x π x 13 = 26π.
The circumference of the circle is 26π.
